Directions

Preheat oven to 350 degrees F (175 degrees C). Spread olive oil into the bottom of a cast-iron skillet or large baking dish.

Bring a large pot of lightly salted water to a boil. Cook spaghetti in the boiling water, stirring occasionally until cooked through but firm to the bite, about 12 minutes; drain.

Stir spaghetti, marinara sauce, diced chicken, onion, pepperoni, green pepper, mushroom pieces, and black olives together in a large bowl; transfer into the prepared cast-iron skillet. Top with mozzarella cheese in a layer and sprinkle with Parmesan cheese.

Bake in the preheated oven until casserole is bubbling, chicken is cooked through, and the cheese topping is lightly browned, about 30 minutes.

Timballo Spaghetti Casserole Haiku: "Change the pasta type. Strand noodles awkward to eat. Needs more parmesan!" I was thrown off by the ingredient list saying "cooked chicken" and instructions saying "bake til chicken is cooked through" so I just ignored that, and made everything as written w/ Costco's Kirkland canned chicken (I'm no can chicken snob; that Kirkland stuff is great!) The spaghetti noodles made this a little difficult to eat (i.e. hard to scoop/stab nummy ingredients all while twirling spaghetti) and 1 TB of parmesan was definitely not enough to sprinkle over the entire top, so we added more when we served it. Made a TON but the leftovers were just as good, if not better; when making again, I'd use a different noodle, reduce the mozzarella, increase the parm, and maybe saute the onions and peppers.

This recipe is good as a guide for throwing a pasta casserole together. Like many others, I modified the recipe to my liking and I used what ingredients I had on hand. I used cavatappi pasta, cut the tomato sauce in half, used sweet red pepper instead of green, used fresh mushrooms, sauteed all vegetables before mixing in and added 1 c of kidney beans. I skipped the pepperoni and added some red pepper flakes. So, I guess it is not really the same recipe that I am reviewing but my point is the recipe is flexible. I also mixed 1/2c. Parmesean cheese into the casserole and didn't put any on top. I cut the mozzerella in half. Overall, it was good and I will definitely make other variations in the future.

Very good! I gave this 4 stars because I changed several things due to items I had on-hand. I cut the recipe in half for three adults. Used turkey pepperoni because that's what we like. Left out the green pepper and black olives as I didn't have any. Used mini rigatoni for the pasta and added extra sauce and extra chicken and the mushrooms. Sprinkled shredded cheddar and monterey jack mix on top, then shredded parmesan. My family loved it and would definitely make it again with the green pepper and olives. It was a great way to use leftover chicken! Also, I baked it in a pottery pie plate so it looked pretty, too.
